Set up issues with 550c

I dont have anyone locally who can help me so I'll try my hand here.

I bought a 550c (all the bells and whistles), but I am not sure its setup correctly. Or at least optimally.

9mm carbide seating decapping die:
I am getting this "coke bottle" taper in the middle of the casing. Brass is mixed fc and blazer. No matter what I do, I'm always getting it. I called dillon and the guy said it was normal. He didnt seem like he wanted to talk (they never do), so I figured I'd ask somewhere else. Why do these dies do this, while others dont? Is there anyway to stop these dies from doing this? It's more of an OCD thing, but looking at the carridge/case spec, the taper is in the wrong area. I'd prefer to load cartridges without random tapers and it be in spec. Will 223 and 308 dies do this too if I buy dillon rifle dies down the line?

Moving on, the decapping system in this die is not great. About 1 in 10 will be decapped and the primer will be sent flying to the floor or will get stuck in the primer slide/track plate, rendering the machine temporarily useless. How can I fix this? The die has one of those spring loaded pins for decapping.

Finally. The last problem I seem to be having is the powder rod. In order for the powder bar to fully go back, I have to rotate the whole powder hopper assembly counter clockwise a little bit. It looks as if its putting a bind on the powder rod because it's no longer perfectly parallel to the deal that connects under the shell plate. If I perfectly align the rod (perfect vertical), it binds up and the powder slide doesn't go all the way back. Is there a video on how to set this up correctly?

I've got all the dies setup and loaded about 5 test rounds (no powder, no primers). Everything is consistent between the 5 rounds (for mixed brass), just not sure why on having these problems. I plan to load my first live rounds this week and I thought I'd ask before I start to load them up.

I only have a hodgon loading manual l, but it doesn't contain info for Barry's bullets. All the bullets I have are 124 weight. Can I use the hodgon charge weights for 124 gr? Or do I need to buy a different manual?

Here is my setup:
Fc and blazer brass
Hodgon cfe pistol
124 Barry's (I have 250 round nose, 250 round nose hollow base, and 250 flat nose hollowpoint)
Cci small pistol primers

Is the charge rate the same for all bullets across the board? Will primarily be shot of glocks and an ar9 or two. Any help is appreciated. TIA.

RE: Set up issues with 550c

9mm is a tapered case, not a straightwall. When the case is sized, the neck portion of the case is slightly undersized, to ensure sufficient neck tension on the bullet to hold it securely. Seating a bullet expands the neck to the depth of the bullet, resulting in a remaining narrow section just below where the bullet stops going into the case. This is normal. This is unique to the 9mm cartridge.
On the depriming, this is more likely to occur with the Speer brass, due to the anvil configuration of the CCI primers being used. The primer is temporarily sticking onto the tip of the pin. The spring action snaps the pin down to dislodge any stuck primers.

There is a video on our website that shows the correct hookup of the return rod. Most importantly, the rod goes into the oval hole in the rear plate, and comes out the round hole in the front plate.
You can use most of the data in your manual for the Berrys Bullets, with the caveat that you do not want to exceed 1200 fps with plated bullets. Stay below the maximum charges and you'll be fine. The bigger issue is not to overcrimp plated bullets. Doing so can crack the plated material, resulting in part of the jacket remaining in the barrel after firing. Crimp enough to remove any case flaring, but no more.

RE: Set up issues with 550c

Thank you for the info. Is this the video you are talking about?

My powder rod does not have that 15°-ish bend near the top of the hopper. Its 100% straight (until it takes the 90° turn). Is my powder rod defective? Here is the only picture I have of my 550. Although you can see the rod is straight.

I will recheck my crimp die when I get home. Thank you again.

Your straight rod is fine. My 550C's rod is also straight and I don't worry about it being slightly off vertical.
